Dummy Encrypt

[hemlet]

It wlll add a random number between 0-9 to every sencond charcter in a string i find it very usfull if u are trying to use base64 on a more protected level as if u encrypt the same string twice the output would be different as it insterts random numbers even tho this isent as advance as most encryption tech's it would be a good addition to add to others to make them that little bit more secure from prying eyes.

code :

function dummy_encode($str) {
$len = strlen($str);
$str1=0;
$final="";
while ($str1 < $len) {
$final = $final.substr($str, $str1, 1);
$str1++;
$final = $final.rand(0,9);
}
return $final;
}
function dummy_decode($str) {
$len = strlen($str);
$str1=0;
$final="";
while ($str1 < $len) {
$final = $final.substr($str, $str1, 1);
$str1=$str1+2;
}
return $final;
}

please your advise ???

regards,
